ENTER Keypress Event Only Handled Once?

Jun 22, 2010

I am trying to add to items to a combobox by using the "enter" key. It does work when I add the first item, but if I manually clear the box and add another items it does not get added to the list.

(1) I click in the combobox and type "hello" and press the "enter" key

(2) I click on the dropdown arrow and see that "hello" is in the list

(3) I select "hello" in the box and erase it, item is still in the list

(4) I type "goodbye" in the box and press the "enter" key

(5) "hello" is still in the list but "goodbye" is not

Here is the code:

Private Sub CopyrightCombo_Keypress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles CopyrightCombo.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then

[code].....

if I comment the if/end if line and type "hello" the items added to the combobox list are: "h", "he", "hel", "hell", "hello" wich makes sens since the add items is run on every keypress? I know that my commands for adding items is good, I know that my keypress event is handled properly but not when I specify using the "enter" key.

How To Handle Enter KeyPress Event

Jul 19, 2010

I am using the Event Handler below for the Enter Key Press Event, it is running when ever any of the keys is pressed. This is not so much a problem when the app. is running, unnecessary yes. It is giving me problems when ever I am Debugging using Breakpoints. How can I change the Handler so it only runs when the Enter Key is Pressed, doing away with the If statement?

Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
If e.KeyChar = Chr(Keys.Enter) Then
'Different code blocks will run here depending on what
'TextBox or Label is selected.
End If
End Sub

Adding Item To Listbox With Enter Keypress

Feb 10, 2009

I have been out of VB since VB 6, but am back into it to write a basic app. I have created a listbox and am able to add data to it from a textbox via a command button. However, I want to give the user the option to simply press the enter key after they have entered the info the textbox, instead of clicking on the command button. I tried calling the function the command button is using from the "ENTER" event on the textbox, but all that does is execute the function when I click on the textbox? I'm sure this is very simple. What am I missing?

Cancel Dialog - Handling Enter Keypress

Apr 4, 2011

I'm building a Dialog in Winforms. It's got the two OK and Cancel buttons that are there when you create it, which is what I want. In this dialog I also have a TextBox and a Sub (coding in VB.NET) that handles its KeyPress event. I need stuff to happen when the 'Enter' key is pressed. Now, I've done such KeyPress handling times and times again. This situation, however, is different, because as soon as 'Enter' key is pressed, the dialog automatically assumes you're pressing the 'OK' button, returns a result and closes.

In both the Designer and the actual form when running the application, the OK button is highlight, which means is has some kind of a focus (for the lack of a better term) at all times. How can I disable this feature of a dialog? When I debug my code, pressing enter does not even get to the sub handling the KeyPress event. It simply closes the dialog and returns the result, therefore I can't really step through the code and see what happens behind the scenes. To restate the question, how can I disable this functionality?

Asp.net - Cancelling The Keypress [Enter] Action On A Telerik RadGrid

Feb 7, 2012

I have a Telerik Radgrid containing all the valid usernames and passwords that can be used to unlock functionnalities on my web page. The password is encrypted, so you have to click the row to decrypt and show the actual password. All usernames and passwords can be changed by an admin When the admin presses [ENTER] to submit the new username/password combination (instead of pressing the submit button), the new combination is actually submitted (which is fine).

Credits-style Scrolling Textbox And Form Detecting A Enter Keypress?

Mar 8, 2012

I have two issues. The first is that I want to make a textbox scrolling similar to how credits scroll. I don't want it to move on the form, just to scrolling the text down a line/pixel. I thought I could do it with the "Lines" element, but I'm not exactly sure how to execute it.

The other problem is with my flash screen. Right now I have it set so when a button is click, it goes onto the main form. I don't want to use the button but rather have it so if Enter is pressed at any time, it'll go to the main form. All the solutions I've tried to use involve the "e.Keycode" code, but for some reason its unavailable.

Passes The Path Of A File To The Process?

Jun 10, 2011

I have a fairly simple piece of code for viewing files System.Diagnostics.Process.Start(tFileInfo.FullName

Basically passes the path of a file to the process and let Windows deal with how to open it. Have also tried Dim myProcess As New System.Diagnostics.Process

[Code]...

Works beautifully on my machine, but on three others i have tested it on, it opens PDF and TXT files no problem, but as soon as I attempt to open a Word file or an Excel file I get "There is not enough memory or disk space to open Word" and similar in Excel if the application is not already open. If the Office app is open, the code works perfectly. Has anyone come across this before?

Moving PictureBox And Increment Score When Passes Over Object

Feb 20, 2012

Trying to write a very simple game moving PictureBox2 around with keys and when it passes over another object such as PictureBox1 the score is incremented and then PictureBox1 is disabled/removed. Problem is that it disappears but every time you pass over that area it still increments the score further as if the object was there still.

Here is current code, but have also tried hide, dispose and Controls.remove with no luck.
If PictureBox2.Bounds.IntersectsWith(PictureBox1.Bounds) Then
score = score + 1
Label1.Text = score
PictureBox1.Enabled = False
PictureBox1.Visible = False

Validating Form Input And Running Function Only If It Passes

Jan 19, 2010

In my .NET porject, I have to run a lot of validation on 4/5 fields. This validation checks if certain fields have errors, for example: the name field is not allowed to have numbers or symbols. If all these checks are passed, I need to execute a SQL query to pull some data out of the database. I could have it with a lot of nested IFs, and run the function at the end once it passes them all, but this will translate into about 12 nested IFs, and it seems a really bulky way to do it. I have also thought about setting a boolean value after every check, and if the value is 1 then don't run the function, else do. But of course this gets overwritten by other checks that pass.

.NET WebBrowser Control's DocumentCompleted Event Passes No PDisp Argument?

Sep 6, 2011

I have some experience developing for VBA inside Office apps, but I am quite new to VB.NET, and I just noticed that its WebBrowser control is a bit different from that one I used to reference via ShDocVw to use in my VBA Forms.ShDocVw.WebBrowser had the DocumentComplete event, which passed these arguments: URL as string and pDisp as object..NET WebBrowser has the DocumentCompleted event, in which i successfully found e.URL.ToString, but I couldn't find nothing similar to the pDisp object.

This is critical to me on migrating my project from VBA to VB.NET, for I need to handle particular IFrames when they complete loading, which I only could do by getting pDisp's document property. So I need help on learning how to do the same thing with this .NET WebBrowser control, and/or how to reference and use good ole ShDocVw.WebBroser in my Visual Studio project, to embed it in my forms.

DataGridView DateTime Colomn (Also) Passes Current Date When Only Entering Time

Apr 19, 2010

I am building an application that needs to store different time of day values in dateTime fields of an Access database.I am trying to enter the time value's via a DataGridView using TextBoxColomn s.The coloms are formatted with the defaultCellStyle property to show only the time part of the datetime.After i save the entered data and look in the database itself, i see not only the time, but also the (current) date in the datetimefields. This raises a problem when i want to compare the timevalues later on in the functionality of the program i am building.(Of course it is simple to seperate the date and time part in coding of the program, but it would be more elegant (i think) if i could just save only the time part in the database (and have the date part of de datetimes left to 0))I have tryed via the CellFormatting and the CellParsing events, but no luck.I am new to visual basic and probebly missing out on something.

Login Landing Page That Subsequently Passes Username/pw To Other Login Pages?

Dec 28, 2011

It is simply a "Y" in the road. If they are Company A, then I want to send the username and password over to that website and log them in as if they typed it in there. If they are Company B, then the same thing but with a different website. I do not know the term for this, so the google results are not very pretty.I can not do this with a query string (not that I'd want to anyway) as I do not want the username/pw to be visible.Here is the other weird thing. This can be done via a simple HTML <FORM> and Submit button as I have tested it. But I want to do it all in VB.NET code. How is it that it is possible with some simple HTML but not possible in VB.NET? I guess it could be a security thing, right? What do the good guys like us do when we legitimately just want our employees to go to one login page, enter their username/pw, and then (based on their username) send them to either pageA.aspx or PageB.aspx which receives their username/pw that they only entered once before on the first page?

Form ShowDialog Disappears

Feb 24, 2009

I have a form that I am using to search for records in a dataset, it has a text box for entry of the search criteria and a 'Search' button to initiate the editing of the entry and .Filter on the BindingSource. This is one form in a project with many, when I show it using .ShowDialog it always disappears, (not visible and not loaded) after the 'Search' button is clicked, I have stepped through and there is no .Hide or .Close that it encounters, it performs all of the logic correctly but control is returned to the main form it was shown from. When I use the .Show method, I do not have this problem.

Forms :: Showdialog Within Another Thread

Jul 16, 2010

where I am starting another thread which opens a form. Succinctly, it is an animated "Please wait.. processing" type of form. The issue is that I want to make this form a child form of the parent (main thread or main GUI) when I open it.The issue is that I prefer to use frmProcessing.ShowDialog(frmMain) instead of just frmProcessing.Show, because of form disappearing issues. It, of course, gives me an error of illegal cross thread operation. My question is, how do I perform frmProcessing.ShowDialog(frmMain) to show from within another thread, that the newly opened form is actually a child of the main thread. Is there a better way for me to make a small processing form telling the user to be patient while background processes are working? [code]
